United States Patent This invention relates to an anchoring device forvthe marginal edge portions of a carpet or the like oor'covering forfirmly securing and anchoringithe carpetin po sition. p

Heretofore, it has been a problem rin anchoring car pets t`o the floorto provide adequate securing means-for Normally the anchoring devices`have been made-of soft bendable metals and the securing-tangs'have thecarpet.

been Ianced out from the vmetal so as to bite into the However, being ofsoft or bendablev material, pullson the carpet have caused the tangs tobendA back ror to break olf and release the carpet. n

The present invention overcomes these difculties V,by providing ananchoring means which willi securely hold the carpet in position andwhich comprises a simplified 'and inexpensive binding and/or anchoringmeans which can be easilyr andV quickly fabricated and installed.

This is accomplished by providing the anchoringmember', which-may bemade of aluminum, brass, plastic' o r other bendable material, with athickened `rib extending therea'long and by inserting through "the ribso asto project above the base, spikes of material? stronger tlian'thebase material which will pierce the back of the carpet andi effectivelyhold vthe carpet against release from! the anchoring means. Preferably,the ribs extend downwardly from the base, which is adapted' to besecured to the oor, `andY are provided with .means'whereby the .nailscan befreadily driven therethroughfso as to pierce the ribandprojectabove the base.

The present invention is aspecies of Ithe'invention shown and claimedinY my copending application Serial No. 491,375 and now Patent No.2,820,980, issuedlan. .28, 1958. Y

Inone form of the invention the base is provided-with a rearwardly andupwardly extending cover .piece'fatits forward end which is adapted tobebent down oventhe carpet to provide a protective binding or 4covertherefor.

In another formof the invention the Vbase is provided with a pair ofdependingribs Vwiththe free-"fforwa-rdedge portionv of the base beingadapted to receive -the-tucked -in carpetedge toV hold it in position; v

Ak feature of the invention residesin the fact 'that-.the

attaching strip can be made by Vusing anfeXtruded-section 'and by merelydriving the nails therethrough-from the The extruded strip can be ofrelativelysoft the yrequired underside. lmaterial `and can be readily`severedvinto lengths.

Another feature of. the inventionresides-innovel means y ICC Fig. 4 is aview similar to Fig. 1 showing another form of the invention.

Fig. 5 shows the anchor strip of Fig. l secured lto a cement' iloor.

Fig. 6 is a top plan View of the fastening plate used in Fig. 5 tosecure the attaching device to the door. Fig. 7 is a section taken alonglines 7-7 of Fig. 6.

As shown in the drawings, one form of the anchor means of the presentinvention comprises an extruded section' 10 of aluminum, brass, plasticor other bendable material and provides a base member 11 having athickened rib portion 12 and having at its forward edge a downwardlyextending nosepiece 13 adapted to be pressed tightly against the floorwhen the anchoring member is secured thereto by nails 14 or othersuitable means passing through elongate slots 11a in the base as shownin Figs. l and 2. The anchor member is adapted to be inserted under theedge of the carpet 15 with the base supporting the edge of the carpet.When the anchoring member is to serve as a binding means, it is providedat its forward edge with an upwardly and rearwardly extending protectivemember 16 adapted to be bent down 'and' cover the edge las shown in Fig.l. In order to hold the carpet in position, the present invention.provides a plurality of steel spikes 17 which are much stronger thanthe material of the base and which are driven through the rib. at spacedintervals soas to extend above the base and incline toward the edge ofthe carpet so as to pierce the back of the carpet as shown in Fig. 1. Ifthe carpet is to be used with the usual padding, the ribs are formed toproject downwardly and are of a height substantially equalto the padding18 as shown in Fig. l.

While the spikes may be driven into the rib in any suitable manner, inthe preferred form of the invention the rib is grooved at 1'9 so as toproduce a transverse portion 20 of vthin crossesection throug'hwhich thespikes or nails can be driven. In the illustrated form of the inventiona pair of grooves Z1, 22 are employed resulting kin a rib of H-shapecross-section, with the cross web of the H constituting the transverseportion 20. The walls of the grooves are spaced apart a distancevslightly less than the diameter of the nail so that as the nail isdriven through the rib, it will not only pierce the transverse portionbut it will be frictionally gripped by the walls of the grooves.

Under some circumstances it may be desired to secure the anchoringdevice to a concrete or the like oor 23 by means of cement 24 as shownin Figs. 5 through 7. In this case a perforated plate 25 is providedwith an upwardly extending `tongue 26 which is adapted to be passedvthrough the elongate aperture 11a and bent over as shown in Fig. 5. Ininstalling this type of mounting means, it is preferred to place thecement on the oor, insert the tongues of the plate into the slot,position the strip on the floor and locate the plates by the position ofthe strip. The strip is then removed and the cement is permitted toharden. After' the cement is hardened, the anchoring strip is positionedover the tongues and the upwardly extending tongues arefolded over asshown in Fig. 5 lto securely fasten the anchoring means in place.Further, -it will be noted that `the downwardly extending nosepiece notvonly seals'the edge of the anchoring means at the floor but alsoprovides clearance under tbase to accommodate the plate 25 when theanchoring means is secured thereby. f

In the form of the invention shown in Fig. 4 which is preferable for usealong walls where protection of the edge of the carpet is not necessary,the base 31 is provided with a plurality of thickened ribs. While thenumber of ribs `may vary, in the illustrated form of the invention, Iemploy a pair of depending ribs 32, 33 similar to rib 12'.

In the preferred form of the invention the ribs are arranged with oneadjacent the rear edge and the other spaced inwardly from the front edgeof the base so as to provide a projecting free edge portionvlb spacedabove the ioor and under which the edge of the carpet may be tucked.

Each of the ribs is provided with a plurality of spaced spikes or nails34, as shown in Fig. 4, which extend through the ribs and above the baseso as to securely bite into or pierce the back of the carpet l5 and holdit in position. The anchoring member of Fig. 4 is provided withapertures 31a in the base similar to those described in connection withFig. l and can be secured by nails ll4 or by the cementing clips -ofFig. 6 as required.

From the foregoing it will be seen that l have provided a novel anchorstrip which can be readily made and assembled and which includes anextruded section of readily bendable material, such as aluminum, brass,plastic or rubber, which can be severed into the desired lengths. Thestrip is provided with nails or the like which are mounted in ribs inthe strip and are stronger than the strip to provide an adequate anchorfor the carpet. The anchor strip of the present invention can be readilymounted by being fastened with nails or the like or can be cemented downand anchored in the novel combination disclosed herein. Also, thepresent invention can be formed as binding strips with protectiveportions extending over the edge of the strips as are used for exposededges of carpet, or can be used to anchor the edge of the carpetadjacent the wall.

Variations and modications may be made lwithin the scope of the claimsand portions of the improvements may be used without others.
